LOGSE-LEAF BINDER.

appiicatioiried october 2r, 1924.,` serial No. :f4-e617.. Renewed December 24, 192e.

The object of myinvention is to devise a novel binder 4wherein if desired the` cover and the binder canbe'made from a single piece of material. v, l ,l

With the above and other objects in viewk which will hereinafter appear, my invention comprehends a novel construction of. loose leaf binder. V l. i

It further comprehends a novel loose lleaf binder in which the backing and binder can bemade from a single sheet of material.

It further comprehendsa novel loose leaf binder in which the binderv isformed by a folded portion of material, the base of which is secured together in any'desired manner,V

one ofthe folds'having a hook, and means being also provided for scoring the *filing sheets. n

, Other novel features of construction and advantage will. hereinafter more clearly appear in thel detailed description and `the v y v Y e vsheets as 12, see Figure 7, to form appended claims.

For the purpose drawing a. typical embodiment "of it,v which, in[practiceiwill give reliable and satisfactory results. It is, however, to, be under-` stood that this embodiment isv typical only and that the various instrumentalities of which my invention consists can bevariously arranged and organized, and that the invention is not limited to the precise rarrangement `and organization of these instrumenl different scale Vparticularly the'manner inwhich a rsheet is scored. e

Figure 7 is a'sectional elevation of a scored sheet for insertion in the binder.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings: v 1 designates a blank of sheet material from which the backing or cover and the binder are formed, tlieblank being scoredy as`at2 to of illustratingD the invention, I have shown in the accompanying the sheets into position.

y The ,eentmiporaenef ,the .blank 1 is reid4 yed on.. the scored or rweakened lines to form'v the binder, seen in Figure 2, and from which V A itwill be seen that the fold' 6 has an inturned hook vportion or lockingiapv 7l 8 is an inter mediate spacing yfold connected with' an outer fold 9kwhichmayfbe ofV different heighth than thaty ofthe y fold. 6.

flat strip of material yllyse'curied thereto' atfits fastening means. l i Y This strip 711 enables one tok score the rearwardlyk extending fiange or flap 13.

The cover 3 has secured `to it, for example,

by adhesive,a covering stripv 14.5,y Theinner portion of the hook 7 .isv cutaway as "at 15y t0 form a tongue 16 which facilitates sliding The slot 17 formed between*` the and k.the fold 9 isclosed at ,one end bymeans of the U-shaped strip 18 which forms a sheet stop' and which is secured to the folds 6 and 9 in any vdesired manner.

The sheets to be assembled in the binder are inserted, as shown vin Figure 6in dotted lines, beneath the scoring stripll and the juxtaposed side ofthe coverclosedthereby forming on they lsheet the rearwardly inclinedlocking or holding flap 13. f The sheet is then brought into a position to have the flap k13 be received beneaththe hook 7 and is n slidforwardly until is strikes thestop 18.

My present form of loose leaf binder can be very economically manufactured as the The fold 9 hassecured to its Vcuter face a y i* binder and cover are formed from a single sheet of material which is preferably paper; e

It is more Vparticularly,designedv for a loose `leaf binder for schools which canfbeso cheaplyl manufactured Vthat it, with a dozen or more sheets of paper, can bev sold yfor avk few cents. f

If vadditional sheets are desired they can V.be removed from an ordinary4 paper' Spad,

scored, assembled and inserted one by one in the binder.v c

The folds are juxtaposed and secured'to-v ltogether or gether in such a manner that the sheets are resiliently secured between 'the folds and can only be removed by sliding them longitudinally of the binder.

In a co-pending application, I have described and claimed a loose leaf binder cover sections and recom-sheet retaining fineans, the latter being formed by a double thickness of the sheet bent to a hook shape formation.

' 2. A loose leaf binder comprising an integral'sheet of material folded to forni cover sections `and outer and intermediate folds one of said` outer folds terminating Vin a sheetretaining flap, an independent strip disposed transversely of the binder and forming sheet-scoring means carried by one of l*said flaps, and securing means for said asl folds.

3. A loose leaf binder comprising Aa cover and a binding portion, said binder having a plurality of folds one of which terminates in an inwardly extending iiap of double thickness and extending transversely throughout substantially the width of the binder, forming record-sheet retaining means, and securing means for said foldsn Q l neeaiio record-sheet retaining means7 a strip dis- .f

posed transversely of one of said folds and secured to such fold along the marginal edge Vof the strip to form a scoring device, and

securing means for said folds.

5. A loose leaf binder comprising a cover f section and a binding portion, said binder being formed of an integral piece of material folded upon itself to provideouter folds and an intermediate spacing fold7 one of said outer folds terminating in an inwardly extending sheet-ietainiiig flap, a strip of material secured to one of said folds and extending therefrom to enable a sheet to be scored to be inserted between said strip and its fold7 and securing means for said folds.

(5. il. loose leaf binder having a plurality of folds forming a slottlierebetween, one of said folds terminating in an inwardly extending sheet-retaining iiap, means to secure the folds together, and stop at one end of said slot.

7. A loose leaf binder having a plurality of folds forming a slot therebetween to receive a sheet, one of said folds having an inwardly extending sheet-retaining flap, the nap-carrying fold at one endhavinga portion cut away to facilitate 'the assembling of a record sheet therewith.
